bad pain

I just turned 8 weeks today and last night I was awoken out of my sleep in pain. my lower back and pelvic area was really hurting bad and it made me extremely nauseous.. it went away after about 5-10 minutes.. I can’t help but to wonder what the hell it was that caused that.. it wasn’t any stabbing or sharp pains it was more so pressure in both areas.. I hope baby is ok…. anyone gone through this? no bleeding
